Clinical descriptionCustomBone Service™ represents the only patient-specific implants made of bioceramic coated with hydroxyapatite, developed by Finceramica for the reconstruction of large and complex cranial defects. Unlike conventional techniques, the implant targets not only the aesthetic outcome but also natural bone regeneration, with neurological and psychological benefits for the patient.
The material is a bio-mimetic ceramic based on macro- and microporous hydroxyapatite — the same component that makes up about 70% of human bone. The interconnected porosity promotes rapid cellular colonization, deposition of new bone, and neovascularization of the implant, supporting osseointegration through direct contact with the adjacent vital bone. The material is fully biocompatible, with no risk of viral transmission, and in the event of subsequent trauma it behaves like natural bone. Owing to the manufacturing process, the hydroxyapatite crystals are more resistant to osteoclastic activity (less osteolysis than an autologous graft), undergoing slow, physiological remodeling.
The CustomBone Service™ process starts from the raw data of the patient’s computed tomography (performed according to a dedicated protocol); through 3D reconstruction and stereolithography, a synthetic model of the skull is obtained, then a prototype of the implant, validated together with the surgeon before finalization. The final implant is prepared, refined, inspected, and sterilized, and is delivered in approximately 2 months. Two implants are supplied (primary + spare), to allow an immediate replacement in the event of a second trauma. Fixation is usually performed with simple sutures — rigid fixation methods, which could fracture the porous hydroxyapatite, are not used.
